IMPROVEMENT IN GAS-BURNERS FOR THE IVIANUFACTUHE 0F LAMP-BLACK.

Specification forming part of' Letters Patent No. l'lbq'b, dated March16, 1875; applientien h d January 25, 1875.

To all 'whom t may concern Be it known that I, PETER NEFF, of Gambier,in the county of Knox and State ot Ohio, have invented certain new anduseful Improvements in Burners to be Employed in ManufacturingLamp-Black; and I do hereby declare the following to be a full, clear,and exact dcscription of the invention, such as will enable othersskilled in the art to which it pertains to make and use it, referencebeing had to the accompanying drawings, which form part of thisspeeilication.

This present application (Gase C) is a modieation or slightly differentconstruction ot' the burner, and forms one of a number of applicacations made by lne for certain improvements in gas-burners to be usedin the manufacture of lamp-black.

My invention relates t0 a burner to be applied or employed in themanufacture of lampblaek and consists in forming the said burner with awide open mouth of greater diameter than that of the pipe or stem ot'the burner, and of a disk or plate located in the said mouth for thepurpose of sprezuling` the gas as it emerges from the burner, for thepurposes hereinafter set forth.

In the drawing, Figure l is a plan view of the top of my burner. Fig. 2is a sectional view ofthe same. Fig. 3 is a view oi' a variation of mysaid invention. Fig. fl is another Variation.

In the manufacture of lamp-black from gas it is desirable that the gasshould issue from the burner in sueh a manner as to cause it to beburned at a low temperature, and at the same time so as to waste orpermit to go uneonsulned as little gas as possible. My invention isdesigned to effect this improvement.

A is a service-pipe, or a pipe through which the gas is fed to theburner. B is the burner, into which the ow ot gas is regulated by thestop-eock G. I) is the enlarged or widened mouth of the burner. E is adisk or plate, that is suspended in any suitable manner so as to bepreferably just above the mouth of the burner, and to be about the samesize as the said mouth. It is also made preferably in a dish shape, soas to direct the gas in its mojtion out under the said disk.

The operation is as fellows: Gas, entering the said burner through theteedpipe, enters the enlarged portion, strikes against the under sideofthe disk E, and is directed outward in all directions in a largetlattened shape, as 1n the drawing. In this way the gas is spread into ahollow conical form, and will have but a thin wall of the said gasexposed upon its outside to the oxygen ot the air, the inside beinghollow, or not filled with gas, as would be the ease were the diskdispensed with.

I3 y forming the burner iu this manner, with a wide open mouth and thedisk` B, the gas 1s made to burn with a very slight pressure and at alow temperature. All or nearly all ot' the gas is consumed on thesurface, little, if any, being permitted to rise to the apex ot' thecone, where the heat is usually of sueh intensity as to burn up thecarbon.

Instead 0i' employing the disk E in the mauner shown in Figs. l and 2,the disk may be secured in a position in any suitable manner, as, forinstance, in the manner shown in Fig. or it way be suspended in thecenter by a rod or brace, substantially as shown in Fig. 4, or in anyother suitable manner whereby the disk is held in the enlarged mouth ot'the burner. So, also, the disk may not, necessarily, be dished, as shownin Fig. l, but may be iiat, or any other suitable form, and may extendout to a greater or less extent.

In constructing the burner it maybe formed as shown in Fig. 2, whereinthe enlarged mouth is reduced by successive reducing-,joints until of asize sufficient to attach it to the feed-pipe A, or the said burner maybe east 0r otherwise i'ormed-in the first instance ot' a tapering shape,small at the bottom and large at the top, as shown in Fig. 3; or theburner may be in the i'crm ot' un elbow, as shown in Fig. 4, withoutdeparting from the nature of my invention, which contemplates a burnerwhich has a broad widened mouth and a diminished stein, and a dellectingplate or disk in an open mouth for the purpose of burning gas at a lowtemperature for the manufacture of lampblaek.

This burner is designed for use in any mechanism, or in any place wheregas, either natural or artilicial, is burned in the manufacture of lamp-blaek, the essential feature being that the gas is fcd to the burnerthrough a pipe or orice less than the burner, and is permitted to flowfreely through and out from the burner.

It is obvious from the foregoing that the gas may be burned from the endof a pipe of uniform dimensions, and the flow of gas be governed by thestop-cock, so that the gas iiowing through the diminished orifice formedby the stop-cock Will oW freely to the end of the pipe, Where it isburned.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the wide open mouth O of the burner for use inthe manufacture of lamp-black, of lthe removable deecting-disk D,substantially as and for the purposes described.
